Description
Technical field
The utility model relates to bending tube forming technical field, more particularly, relates to the shaping plug of a kind of side's rectangular bend.
Background technology
Tubing is in bending deformation process, and in neutral line, the force way in outside is inconsistent, and the effect of neutral line material outside tension power is extended, and the effect of being stressed of neutral line inside material is piled up.Along with the reduction of tube wall thickness and bending radius, easily occur drawing crack phenomenon of caving in outside neutral line, easily occur fold unstable phenomenon inside neutral line, bending effect is poor, even occurs bending unsuccessfully.
Along with the development of national economy, all trades and professions are to the demand of bend pipe, and especially the demand of thin-walled multi-curvature minor radius bend pipe increases rapidly, are proposed more and more higher requirement to quality, precision and the working (machining) efficiency etc. that elbow curvature is shaped.The mode of adding plug is generally adopted to ensure the bending effect of tubing at present, but the square rectangular bend generally used in automobile and other industries, because scale is long, bending radius is little, bending curvature is complicated, bending precision high, consider the requirements such as the cost of plug, versatility, flexibility, the forms such as existing ball-and-socket joint plug are difficult to meet the needs that reality is efficient, low cost, high-quality are bending.
Summary of the invention
The purpose of this utility model is to design the shaping plug of a kind of side's rectangular bend, solve and to be difficult under existence conditions to provide suitable plug to meet the long scale of square and rectangular pipe, high accuracy, multi-curvature, problem that minor radius is bending, there is the features such as low cost, high universalizable, high flexibility.
For achieving the above object, the technical solution adopted in the utility model is,
The shaping plug of one side's rectangular bend, is characterized in that, adopts some thin slices to be formed by stacking in the height direction, the bending direction of the thin slice Direction of superposition side of being rectangular bend, and thin slice superposition highly suppose the little 1-3mm of cavity heights of rectangular bend; Described sheet thickness is 0.6 ~ 1.5mm; Described plug establishes the chamfering matched with square rectangular bend inner chamber R angle, and, this rectangular bend inner chamber R angle, plug chamfering side of being greater than.
Preferably, the width of described thin slice must ensure that the one-sided gap of the soft plug of thin slice and tubing inner chamber is at 1 ~ 3mm.
Preferably, thin slice is welded and fixed one end when combining, and makes grinding process; Thin slice other end when combining does not apply any constraint, and arc transition process is done in front end.
Preferably, the chamfering of described plug is R2mm, R4mm, R6mm, R8mm and R10mm five kinds of specifications.
The utility model plug sheet thickness used is 0.6-1.5mm, and material is Q195D or Q235B through process of turning blue.According to the difference of bending tubing appearance and size, the soft plug of described thin slice adopts varying number thin slice to superpose in the height direction, due to the bending direction that thin slice Direction of superposition is square and rectangular pipe material, for ensureing the bending quality of tubing, thin slice superposition highly must suppose the little 1-3mm of the cavity heights of rectangle pipe material.For the welded tube of non-deburring, if weld seam is positioned at this direction, then should ensure that the gap of the soft plug of thin slice and weld seam inner burr is 0.5-1.5mm.
The width of the soft plug of thin slice, the i.e. width of plug thin slice, due to the bending direction perpendicular to square and rectangular pipe material, for improving the bending effect of square and rectangular pipe material, must ensure that the one-sided gap of the soft plug of thin slice and tubing inner chamber is at 1-3mm.For the welded tube of non-deburring, if weld seam is positioned at this direction, also should guarantee, with weld seam inner burr, undue extruding does not occur.
Meanwhile, for ensureing that in BENDING PROCESS, the soft plug of thin slice can be full of the inner chamber of square and rectangular pipe material as far as possible, the chamfering near with bend pipe inner chamber R corner connection must be processed.Consider versatility and the low cost requirement of the soft plug of thin slice, the chamfering of plug should be greater than the R angle of tubing inner chamber, and based on the specification of square and rectangular pipe material existing on market, the chamfering of the soft plug of thin slice adopts R2mm, R4mm, R6mm, R8mm and R10mm five kinds of specifications.
In addition, under the prerequisite of guarantor's rectangle pipe material bending quality, guarantee the ease of use of the soft plug of thin slice, the soft plug of thin slice is welded and fixed one end when combining, and makes grinding process, and according to the difference of plug length, welding region length is 100-300mm.The soft plug of thin slice other end when combining does not apply any constraint, and arc transition process is done in front end, and when ensureing bending, thin slice plug can be free to slide at tubing inner chamber, the bending quality of guarantor's rectangle pipe material, reduces the Core-pulling force requirement of plug.
Compared with existing plug design form, the utility model has the following advantages:
In the actual flexion process of square and rectangular pipe material, especially in thin-walled, complex curvatures, minor radius BENDING PROCESS, the utility model effectively improves the bending quality of square and rectangular pipe material and bending precision, and the interior outside of bend pipe subsides and appearance and size fluctuation etc. is obtained for effective control.The soft plug of the utility model thin slice has the advantages such as flexibility is high, highly versatile, cost are low, processing criterion, long service life, is specially adapted to the long scale of square and rectangular pipe material, high accuracy, complex curvatures and minor radius bending.
